The effects of the thiazides diuretics is to pass out fluid in the kidney.They do this by interfering with the transport of salt and water across certain cells in the kidneys. It tends to have only a week action on the kidneys and as a result the patient doesn’t notice a great increase in urine if this medicine is taken.
My best guess would be C. Assessing a patient's level of compliance with past medical advice. You want to know if they have followed medical advice prior because if they haven't, you would just be wasting your breath.
